Copper cooling plate with multilayer protrusions comprising wear resistant material, for a blast furnace

Abstract:

A cooling plate for use in a blast furnace is described. The cooling plate has a copper body having an inner face containing ribs parallel therebetween, having first extremities and separated by grooves having second extremities. At least one of these grooves containing at least a part of a multilayer protrusion extending between its second extremities and having at least one layer made of a wear resistant material that increases locally the wear resistance of the neighboring ribs.
